A member of your programming team suggests that your rehash() method first convert the key to a String using its toString() method, then hash on the resulting string. Evaluate this idea. Be sure to justify your claims.
What will be an ideal response?
: If the keys are already integers or characters, then converting to a String is simply extra work as the hashing method will then convert those characters in the String back to their ascii values. Otherwise, the idea would work fine, the folding hash technique could be used and all keys would be hashed in the same manner, producing a more even distribution of hash values.
